Playing a CD
If the ignition or radio is turned off, with a CD in the
player, it will stay in the player. When the ignition
or radio is turned on, the CD will start playing where it
stopped, if it was the last selected audio source.
When a CD is inserted, the CD symbol will appear on
the display. As each new track starts to play, the
track number will appear on the display.
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.

If this message is received when tuned to channel 0, there
may be a receiver fault. Consult with your GM dealer.
If this message does not clear within a short period of time,
your receiver may have a fault. Consult with your GM
dealer.
If playing a CD-R, the sound quality may be reduced
due to CD-R quality, the method of recording, the quality
of the music that has been recorded, and the way the
CD-R has been handled. There may be an increase
in skipping, difficulty in finding tracks, and/or difficulty in
loading and ejecting. If these problems occur, check
the bottom surface of the CD. If the surface of the CD is
damaged, such as cracked, broken, or scratched, the
CD will not play properly. If the surface of the CD
is soiled, see Care of Your CDs and DVDs on
page 3-107 for more information.
If there is no apparent damage, try a known good CD.
Do not add any label to a CD, it could get caught in the
CD player. If a CD is recorded on a personal computer
and a description label is needed, try labeling the top of
the recorded CD with a marking pen instead.
